3 Claims.

This invention relates to improvements in fasteners of the rotary bar type for hinged doors.

One object of the inventionis to provide a lever operated rotary bar fastener for a pair of hinged doors, wherein the rotary bar is mounted on one of the doors and has means thereon cooperating with fixed keepers for forcing the door, which carries the bar, to closed position and the bar has direct engagement with the other door of said pair to force the last named door to closed position.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the accompanying drawings forming a part of this specification, Figure 1 is a broken rear elevational view of the body portion of an automobile truck provided with a pair of hinged doors, illustrating my improvements in connection therewith. Figure 2 is a broken vertical sectional view, corresponding substantially to the line 2-2 of Figure 3, said view being on a slightly reduced scale. Figure 3 is a top plan View of the pair of doors shown in Figure 1, taken at the inner end portions of said doors, said view being on an enlarged scale. Figure 4 is a horizontal sectional view, on an enlarged scale, corresponding substantially to the line 64 of Figure 2. Figure 5 is a horizontal sectional view, on an enlarged scale, of the inner end portion of the right hand door shown in Figure 1, corresponding substantially to the line 5-5 of Figure 2. Figure 6 is a vertical sectional view, on an enlarged scale, through the mid portion of the upper end of the rotary operating bar of my improved mechanism. Figure '7 is plan view, on an enlarged scale, of the lower keeper of my improved mechanism, illustrating the operation of the keeper engaging means, showing the same in three difierent positions, one of said positions being shown in full lines and the remaining two being shown in dotted lines.

In said drawings, II] indicates the rear end wall of the body of an automobile truck. The wall I is provided with the usual opening II, closed by a pair of hinged doors I2 and I3, supported along their outer edges by hinges I i-I4. The doors I2 and I3 are of a well-known type employed on automobile trucks, each door having front and rear spaced walls I and I 6.

In carrying out my improvements, I provide the door I2 with a vertically disposed ,Z-bar I! at its inner edge, the web I8 of which forms the vertical end wall of said door structure. The rear flange I 9 of the Z-bar I1 extends inwardly of the door and is fixed to the inner side of the rear wall I 6. The front flange of the Z-bar, which flange is indicated by Zii, projects laterally outwardly from the web I8 thereof and extends along the inner side of the front wall I5 of said door and is secured to said wall in any suitable manner.

The door I3 is also provided with a vertically disposed Z-bar 2i at its inner edge, the web 22 of which forms the vertical end wall of said door. The rear flange 23 of the Z-bar 28 projects laterally outwardly from the web 22 and is fixed to the inner side of the rear wall It of the door I3. The front flange 2d of the Z-bar 2! projects inwardly along the front wall I5 of the door I3 and is fixed to the inner side of said wall.

As will be seen upon reference to Figures 3 and 4, when the doors are in closed position, the flange 20 of the door I2 overhangs the flange 23 of the door I 3. As shown in said figures, the front wall I5 of the door I 2 is preferably extended outwardly beyond the vertical end edge of the flange 20 of the Z-bar I! to overlap the inner edge portion of the door I3 when the doors are closed.

My improved fastener is carried by the door I2, and the front wall I5 of said door is provided with an inwardly offset section 25 between the top and bottom portions of said door, adjacent the inner edge thereof, forming a laterally elongated pocket 26, adapted to receive the operating handle lever of my improved door fastener when the bar and the handle lever thereof are in position to hold the door closed. The door I3 is provided with a vertically extending, outwardly facing rubber strip 21 along its inner edge portion, the strip 2! being mounted on the front side of the flange 23 of said door. The rubber strip 21 is preferably covered by a canvas strip 28 which overlaps the same.

My improved door fastener means proper comprises broadly an operating bar A, keeper engaging end members 13-13 at opposite ends of the bar, an operating handle lever C for said bar, top and bottom keepers D-D with which the end members B-B cooperate, and bearing brackets E-E for the bar A.

The operating bar A is in the form of an elongated tube of circular cross section, mounted on the door I2 at the inner side of the flange 20 of said door. The bar A extends vertically and carries the keeper engaging end members B-B at the top and bottom ends thereof.

Each keeper engaging end member B is in the form of a cylindrical cap providing a socket 29 within which the corresponding end of the bar A adjacent the top and bottom edges of said door;

To hold the bar A against endwise displacement, each end member B is provided with an annular stop collar at its inner end in the form of an annular outstanding flange 32, the flange 32 of the bottom end member being supported on the lower bearing bracket E and that of the top end member being engaged with the underneath side of the top bearing bracket E. The bearing brackets E-E are of the COllll'llOllfiWO-Palt construction, comprising front and rear sections 33 and 34, embracing the corresponding bearing portion of the bar A.

The operating lever C for rotating the bar A is fixed to the latter, being preferably welded there to. The lever C is located so that it swings into the pocket 26 when the doors are forced to closed position, the side wall 35 of the pocket and the Z-bar ll being slotted, as indicated at 36, to ac; commodate the handle lever in its swinging move ment. The usual latch, indicated by 3?, is also provided on the door !2 for locking the lever C in position when the doors are closed.

The keepers 13-13 are of well-known design, each keeper being in the form of a block provided with an inclined cam slot 33 with which the crank pin (it of the corresponding end member B is engageable. The keepers D-D are mounted within the door opening H, above and below the door I2, in proper position to be engaged by the crank pins 3B-39 of the top and bottom end members BB. I

The operation of my improved door fastener is as follows: In closing the doors i2 and 13, the

door i3 is first swung to partly closed position. Then the door i2 is swung partly closed to bring the crank pins 303ii of the operating bar into cooperative relation with the keepers BB, as shown in full lines in Figure '7. The bar A is then rotated incontraclockwise direction, as viewed in Figure 7, engaging the crank pins within the slots 3838 of the keepers and camming the door shut. The relative positions of the crank pin 39 of the lower keeper engaging end member in the slot 33 of the keeper, as it enters the slot and cams the door closed, are shown by the two dotted line positions in Figure '7. As the door 12 is cammed inwardly, the bar A engages the projecting strip 2? of the door I3 to force the latter tightly closed. when the doors have been forced home to closed position, the handle lever C is locked in position by the latch 3'? to maintainthe doors closed.

In opening the doors, the door I2 is cammed outwardly by rotation of the bar A. After it has been thus forced partly open, it is manually swung to completely open position by the attendant, thus leaving the door I3 free to be swung open also.

Iclaim:
